    Abstract: Provided is a method of heat treating a die cast aluminum alloy component. A die cast component has at least one thin walled region with a thickness of ≤5 mm. The alloy has silicon at ≥6.5 mass % to ≤15.5 mass %, copper at ≥0.1 mass % to ≤3.5 mass %, magnesium at ≤0.5 mass %, manganese at ≤0.6 mass %, and chromium at ≤0.6 mass %. The method includes quenching the die cast component at a cooling rate of ≥ about 100° C./second to a first temperature of less than 50° C. and age hardening by heating the die cast component to a second temperature of ≥ about 150° C. for a predetermined duration of time to facilitate formation of particles of Mg2Si in an aluminum alloy matrix. The aluminum alloy treated by the method can form lightweight, high strength, high ductility components.

    Abstract: An aluminum alloy consisting essentially of from greater than 6 wt % to about 12.5 wt % silicon; iron present in an amount up to 0.15 wt %; from about 0.1 wt % to about 0.4 wt % chromium; from about 0.1 wt % to about 3 wt % copper; from about 0.1 wt % to about 0.5 wt % magnesium; from about 0.05 wt % to about 0.1 wt % titanium; less than 0.01 wt % of strontium; and a balance of aluminum and inevitable impurities. The aluminum alloy contains no vanadium. A method for increasing ductility and strength of an aluminum alloy without using vacuum and a T7 heat treatment, the method comprising: casting the molten aluminum alloy by a high pressure die-cast process to form a cast structure. The structural castings formed of the aluminum alloy composition disclosed herein exhibit desirable mechanical properties, such as high strength and high ductility/elongation.

    Abstract: A VPN-based method for a mobile communication terminal to access data securely comprises: when a data security device is operating in the mobile communication terminal, the data security device allows the mobile communication terminal to access an intranet but inhibits the mobile communication terminal from accessing an external network; and when the data security device is not operating in the mobile communication terminal, a VPN server inhibits the mobile communication terminal from accessing the intranet. The data security device is disposed in the mobile communication terminal. The data security device cooperates with the VPN server to inhibit the user of the mobile communication terminal from sending protected files to the external network via a network when the data security device is deactivated and to inhibit applications running on the data security device from accessing networks outside the VPN resources to release the protected files to the external network.
